Best Dive Centres in Phuket
27,621 viewsBy Willy Thuan · Living in Phuket since 1994
Phuket is the main gateway to scuba diving in Thailand’s Andaman Sea, with more than 30 active dive centres on the island. Most day trip boats depart from Chalong Bay on the southeast coast, heading east to
Shark Point, Anemone Reef and the King Cruiser Wreck, or south to
Racha Yai and Racha Noi. The
liveaboard route runs northwest to the Similan Islands, Koh Bon, Koh Tachai, the Surin Archipelago and Richelieu Rock, widely rated one of the best dive sites in the world.
Diving is available all year round. The best conditions are from November to April during the northeast monsoon, when the Similan and Surin national parks are open and visibility can reach 30 metres or more. From May to October, day trips still run to the eastern sites and Racha Islands, where conditions remain good. Water temperature stays around 28 to 30 degrees all year.
First-time divers can join a Discover Scuba Diving introduction with no prior experience required. You get a briefing on the boat and do your first dive in shallow water the same day. A PADI or SSI Open Water certification usually takes three days. Booking your course or liveaboard in advance is a good idea, especially during high season.
Below is a list of reputable dive centres operating around the island. This list is not sponsored and is in no particular order. I have worked with several of them over the years through the site.
How to Choose a Dive Centre in Phuket
With so many operators on the island, picking the right one comes down to a few simple factors. Here is what I look for when someone asks me for a recommendation.
Location matters more than you think. Most day trip boats leave Chalong Pier between 7 am and 8 am, and the transfer from Patong, Kamala or Bang Tao can add 30 to 45 minutes to your morning. If you are staying in the north of the island, a dive centre based in Kamala or Bang Tao will save you a long pickup. If you are in Kata, Karon or Rawai, the south-coast centres are a short drive away.
PADI or SSI? Both are fine. Both agencies are recognised worldwide and the training quality is similar. Pick the centre based on the instructor and the shop, not the logo on the door. Some centres are dual-certified and can teach either system.
Group size is the real differentiator. A ratio of four divers per guide is the standard for a good small-group operation. Larger commercial boats can put eight or more divers with one Divemaster, which changes the experience underwater. Ask before you book.
Day trip vs liveaboard. Day trips are the standard option and run to Racha Yai, Racha Noi, Shark Point, Anemone Reef, the King Cruiser and Phi Phi. If you want to dive the Similan Islands or Richelieu Rock, you need a liveaboard of 3 to 6 days. These only run during high season from November to April.
Beginners and families. Most centres offer Discover Scuba Diving, but some are better set up for first-timers than others. Look for a centre with its own training pool, small group sizes and instructors who speak your language.
Dive Centres on Phuket
Oceanic Dive Center has been in Kata Beach since 1999, making it one of the longer-running dive shops on the island. The current owners, a British husband and wife team, have been active dive instructors in Phuket since 2007 and took over Oceanic in 2010. They are registered under both PADI and SSI, holding SSI Diamond Dive Center status. Courses run from Discover Scuba and Open Water right through to Divemaster. Day trips head to Racha Yai, Racha Noi, Shark Point, Anemone Reef, King Cruiser Wreck and Phi Phi.
They also arrange Similan liveaboards (typically 4 days/4 nights with 14 dives) and Southern Andaman safaris to Hin Daeng, Hin Muang, Koh Haa and Phi Phi. They run their own dive equipment retail shop and are not tied to a single manufacturer, so they can give honest gear advice. Group sizes are kept small. The shop is on Patak Road, walking distance from both Kata and Karon beaches. Snorkelling trips are also available for non-diving companions. Often described by returning customers as “more a club than a dive shop”.

Merlin Divers is an SSI dive centre on Kamala Beach, run by Swiss-German owner Robert Klein, who moved to Phuket over 20 years ago. The original shop was destroyed by the 2004 tsunami and rebuilt at its current location on Rim Had Road, just 20 metres from the beach. They offer all SSI courses from Discover Scuba through to Divemaster. Day trips run to Racha, Phi Phi, Shark Point, Anemone Reef and the King Cruiser Wreck, plus Similan liveaboards during high season.
A big draw is their local west coast half-day trips to around 10 dive sites off Kamala, Surin and Bang Tao. These are rarely visited by other operators, so you often dive without seeing another group. The boat holds a maximum of 8 customers. They are an Aqua Lung Partner Center with one of the largest dive retail sections on the island. A good option if you are staying on the north-central west coast and do not want to travel far for your dive shop. Courses are available in multiple languages.

| Location: Chalong + Khao Lak |
Sea Bees has been running for over 30 years and holds SSI Diamond Instructor Dive Center status. Their headquarters and teaching centre are near the port in Chalong Bay, with additional branches at the Amari Coral Beach Resort in Patong and the JW Marriott in Mai Khao. They also operate out of Khao Lak for Similan access. What sets them apart is that they run their own custom-built fleet of dive boats rather than booking through third parties.
Their 23-metre day trip vessel Excalibur 2 was purpose-built for divers, with a covered sundeck, dive bar and freshly cooked lunches on board. Day trips visit a different destination each day on a fixed weekly schedule, with two to three dives per outing. Maximum group size is four divers per guide. They also run their own bungalow resort near Chalong for divers who want accommodation and diving in one package. Liveaboard safaris of up to 6 days cover the Similans, Koh Bon, Koh Tachai, Surin and Richelieu Rock. One of the larger and more established operations on the island.

| Location: Patong Beach + Chalong Bay |
Thailand Divers has over 18 years of experience running PADI courses and day trips. They operate from two locations: a shop on Rat-U-Thit Road in Patong Beach and boats departing from Chalong Bay. Their day trip boat MV Mermaid visits Racha Yai, Racha Noi, Phi Phi, Shark Point and the King Cruiser Wreck, completing three dives per day. Maximum group size is four certified divers per Divemaster.
All PADI courses are available, from Discover Scuba through to Divemaster and specialities. Hotel transfers anywhere on Phuket Island are included with every trip. Having a base in Patong makes them convenient for travellers staying on that side of the island who do not want to arrange their own transport to Chalong. They cater to both certified fun divers and complete beginners.

Hotel transfers from Rawai, Chalong, Kata, Karon, Patong and Kamala are included. Their location in Rawai makes them a short drive from Chalong Pier, keeping morning pickup times reasonable.

No Gravity is a family-run PADI and SSI Dive Center in the Chalong area, founded by Hungarian instructor Attila in 2007. The team is small, which means more personal attention. All courses are taught in private classes or groups of maximum four students per instructor. They offer the full range of PADI courses from Discover Scuba to Divemaster, plus beach dives at Kata reef and boat day trips to Racha Yai, Racha Noi, Phi Phi, Shark Point and Koh Dok Mai. Similan liveaboards from 2 to 6 days are also available.
They have their own training pool at the Chalong centre for confined water sessions. Non-divers can join on snorkelling and sightseeing trips to Phang Nga Bay, Krabi, Coral Island and Khao Sok. They can also help arrange accommodation near the dive centre. A good fit if you prefer a quieter, more personal setup rather than a large commercial dive operation.

Tech Dive Asia is Thailand’s main technical diving operation, based in Phuket but running trips across Thailand and Southeast Asia.

They offer the full range of RAID technical courses including Deco 40, Deco 50 and Deco 60 (normoxic trimix), plus open circuit and rebreather training.
Guided technical dives cover deep ocean reefs, wrecks, caves and even mines. They cater to both divers taking their first step from recreational into technical diving and experienced tech divers looking for advanced training or guided exploration. Not a place for complete beginners to scuba, but if you already hold an Open Water or Advanced certification and want to push deeper, they can map out the progression.

SSS Phuket has been operating since 2008 on Kata Noi Road, steps from Kata Beach.

Instructors speak English, French, Chinese, Russian, German, Spanish and Thai. Scuba day trips go to Racha Yai, Phi Phi, King Cruiser and Shark Point.
They also run a Coral Reef Creation Project, sinking structures to encourage natural coral growth at local dive sites.

With over 70 courses and activities available year-round, SSS is a good option if you want to combine diving with surfing or freediving during a single trip.

This makes them a good fit for small groups, families or anyone who values privacy on the water.

They run both shared and private half-day and full-day dive tours to sites along and north of Phuket’s west coast. Half-day trips are convenient if you do not want to spend the entire day on a boat, or if you want to combine a morning dive with afternoon activities.
Full-day trips cover the more distant sites. PADI courses are available from beginner to advanced levels. Being one of the few dive centres based on the northwest coast, H2O Sportz is a convenient choice if you are staying around Bang Tao, Laguna, Surin or Cherng Talay and want to avoid the long morning drive down to Chalong.

Insider Tips for Booking a Dive Centre in Phuket
A few things I have learned over the years from booking dives, sending friends to centres and watching the industry change.
Book directly with the dive centre rather than through a hotel tour desk or a general booking site. You get a better price, the centre knows you are coming, and if conditions change they can move you to a different day.
The first boat out of Chalong is usually the best boat. Morning seas are calmer, visibility tends to be better and the dive sites are less crowded. If your centre offers an early departure, take it.
Liveaboards book out fast. If you want a Similan trip in January or February, book by October at the latest. The better boats are full three to four months in advance during peak season.
Never drink alcohol the night before a dive and never skip a dive surface interval. Sounds obvious, but every season I hear about someone ignoring this. Decompression issues are not a joke.
Ask about cancellation policy before you pay. Rough seas do happen, especially in May to October. Most good centres will reschedule or refund if the trip cannot run safely.
If you are nervous about your first dive, say so. Good instructors will give you extra time in the shallows. The dives where I have seen people panic are almost always the ones where they pretended to be fine.
Scuba Diving in Phuket Through the Years
Phuket diving in the 1990s was a smaller world. When I arrived in 1994, there were maybe a dozen dive shops on the island, most of them run by Western instructors who had moved here for the lifestyle. Chalong Bay was already the main departure point, but the boats were smaller, the sites were quieter and the Similan Islands felt genuinely remote.
The King Cruiser passenger ferry sank in May 1997 after hitting Anemone Reef. Nobody died, but the wreck quickly became one of the most visited dive sites in the Andaman Sea and it is still on every day trip itinerary today. It is probably the single most important event in shaping modern Phuket day trip diving.
The 2004 Indian Ocean tsunami hit the industry hard. Dive shops on Patong, Kamala and Khao Lak were destroyed. Several centres did not come back. The ones that rebuilt, like Merlin Divers in Kamala, are still operating today and the community that survived is tighter for it.
By the 2010s, the industry had shifted. PADI 5 Star centres and SSI Diamond centres became the norm rather than the exception. Group sizes came down as divers started demanding better ratios. Liveaboards became more comfortable, with some now running at proper cruise-boat standards.
The 2020 to 2022 Covid years emptied the island. A lot of operators closed permanently. The ones still here in 2026 are the survivors, and on the whole the quality has gone up. There are fewer dodgy operators than there used to be, and the centres on this list have all been through more than one hard cycle.
Coral bleaching has become the ongoing concern. Warmer sea temperatures in 2010, 2016 and again in 2024 damaged reefs across the Andaman. The Similan Islands have been closed to diving at various points for reef recovery. The good operators now include environmental briefings as standard, and projects like the SSS Coral Reef Creation at Kata show the industry taking its own role in reef health more seriously.
